cppcheck is another tool to be investigated.

It would be a nice practice for wide character manipulation.

I am wondering if `SIGCONT` should be handled or not from the perspective of usability.

Check the following materials in advance: * [PicoRV32](https://github.com/YosysHQ/picorv32): `ENABLE_COUNTERS64` (default = 1) This parameter enables support for the RDCYCLEH, RDTIMEH, and RDINSTRETH instructions. If this parameter is set to 0,...

[fastrv32](https://github.com/jserv/wip-fastrv32) is another reference for implementing timer stuff.

Sample RISC-V assembly program using performance counter: ```assembly .section .text .global _get_cycles .type _get_cycles, @function _get_cycles: csrr a0, minstret csrr a1, minstreth ret ```

The author of [rv8](https://github.com/michaeljclark/rv8) showed a neat technique to render histogram. See https://github.com/microsoft/mimalloc/pull/529
